Mönestam EI. Long-term results of cataract surgery in type 2 diabetics, a 20-year prospective longitudinal study. Acta Ophthalmol 2024; 102:58-67. [PMID: 37140144 DOI: 10.1111/aos.15684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 03/30/2023] [Accepted: 04/21/2023] [Indexed: 05/05/2023]
Abstract
PURPOSE To investigate the 20-year outcome, in best-corrected visual acuity (BCVA), and subjective visual function (VF-questionnaire, VF-14) after cataract surgery in type 2 diabetics, compared with non-diabetics. METHODS 109 type 2 diabetics and 698 non-diabetics, who had cataract surgery during 1 year at one institution, were included in this prospective, longitudinal, population-based cohort study. BCVA and VF-14 responses were recorded pre- and postoperatively, and every 5 years up to 20 years after surgery. Retinopathy was graded before surgery. RESULTS There was no significant difference between diabetics and non-diabetics, in change in BCVA from 10 years or more after surgery, p = 0.45, p = 0.44 and p = 0.83, at 10, 15 and 20 years, respectively, as well as in self-perceived visual function (VF-14) at any time after surgery, p = 0.72, p = 0.20 and p = 0.78, 10-20 years, respectively. At any follow-up, there was no significant difference in BCVA in relation to retinopathy level before surgery, p = 0.1 at 20 years. There was a trend from 10 years after surgery and onward that patients with no retinopathy at baseline lost fewer letters during the 20 years than diabetics with retinopathy. Patients with known type 2 diabetes at surgery had a significantly lower survival compared with the non-diabetics at each follow-up, p = 0.003. CONCLUSION In surviving diabetics, BCVA and subjective visual function were retained in most cases up to 20 years after cataract surgery. Cataract extraction is effective in causing a sustainable improvement in visual function also in type 2 diabetics. Knowledge of these long-term outcomes is essential when counselling diabetics for cataract surgery.

Pseudophakic macular edema in nondiabetic and diabetic patients without diabetic retinopathy treated with intravitreal dexamethasone implant. Int J Retina Vitreous 2023; 9:56. [PMID: 37723594 PMCID: PMC10506302 DOI: 10.1186/s40942-023-00489-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 08/14/2023] [Indexed: 09/20/2023] Open
Abstract
BACKGROUND The purpose of this study was to compare the impact of intravitreal dexamethasone (DEX) implant during a 12-month period in nondiabetic and diabetic patients without diabetic retinopathy (DR) as a treatment for refractory pseudophakic cystoid macular edema (PCME) following prior treatment with topical nepafenac 0.1% and prednisolone 1%. METHODS Forty-two consecutive medical records of patients diagnosed with PCME after uneventful cataract surgery were included. The outcomes measured included best corrected visual acuity (BCVA) and central foveal thickness (CFT). Linear regression analysis was statistically applied. RESULTS Following topical treatment, nondiabetic and diabetic subjects presented a mean ± SD gain of - 0.11 ± 0.11 and - 0.18 ± 0.11 BCVA logMAR and a CFT reduction of - 43.42 ± 53.66 µm and - 58.76 ± 36.28 µm, respectively. The mean BCVA gain at month 12 subsequent to DEX implantation was - 0.35 ± 0.17 in nondiabetic (p < 0.001) and - 0.55 ± 0.26 in diabetic patients (p < 0.001), with CFT reductions of - 195.71 ± 93.23 µm (p < 0.001) and - 260.81 ± 198.69 µm (p < 0.001), respectively. Patients who responded with better VA after topical treatment presented better visual outcomes at month 12 following DEX implantation (r2 = 0.46; rho = - 0.71, p < 0.01). CONCLUSION Nondiabetic and diabetic patients without DR demonstrated similar results after DEX implant after combined topical therapy, suggesting that selected diabetic patients may have a response comparable to that of nondiabetic patients with PCME.

Abstract
PURPOSE OF REVIEW To review most recent studies and clinical trials regarding pathogenesis, treatment, and prevention of inflammation after the cataract surgery. RECENT FINDINGS FLACS gave opportunity to evaluate inflammatory cytokines in the aqueous humour right after the laser procedure, which led to acknowledging the inflammation pathogenesis during the phacoemulsification. Although there is still a lack of evidence, which would prove the long-term benefit of NSAIDs, they are indicated and effective when risk factors for PCME are present. PREMED studies showed that combination of NSAID and steroids after the surgery for healthy subjects is cost-effective. The triamcinolone injection together with topical steroids and NSAIDs for diabetic patients after the cataract surgery was the most cost-effective in preventing PCME according to the PREMED. Dropless cataract surgery is another emerging topic: dexamethasone implants and suspensions look promising as we await more clinical trials with drug-loaded IOLs. SUMMARY Inflammation after the cataract surgery can be prevented, and these methods are one of the most essential topics with growing phacoemulsification rate. Topical NSAIDs are cost-effective not only for patients with risk factors for PCME but also for healthy subjects. New dropless techniques are being successfully introduced in the clinical practice.

The Association Between Glycaemic Control, Renal Function and Post-operative Ophthalmic Complications in People With Diabetes Undergoing Cataract Surgery-A Single-Centre Retrospective Analysis. Diabetes Ther 2022; 13:723-732. [PMID: 35278194 PMCID: PMC8991233 DOI: 10.1007/s13300-022-01241-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 02/23/2022] [Indexed: 11/14/2022] Open
Abstract
INTRODUCTION In general surgery, it has been shown that poor peri-operative diabetes control, as measured by glycated haemoglobin (HbA1c), is associated with adverse post-operative outcomes. National data for the UK suggest that the post-operative complication rate for cataract surgery is 2.8%. It is unknown whether people with diabetes who undergo cataract surgery are also at increased risk. METHODS This single-centre retrospective study looked at the association of peri-operative HbA1c and estimated glomerular filtration rate (eGFR) with the risk of post-operative complications in people undergoing phacoemulsification and intraocular lens implantation under local anaesthesia during 2016. RESULTS 4401 individuals had cataract surgery. Of these, 34.6% (1525) had diabetes. Of those with diabetes, 114 (7.5%) developed a post-operative ophthalmological complication (as defined by the Royal College of Ophthalmologists) necessitating at least one eye clinic appointment. Mean HbA1c did not differ between those who did and those who did not develop complications (52 vs 50 mmol/mol, p = 0.12). After adjustment, HbA1c was not a significant risk (OR 1.00; 95% CI: 0.99-1.05; p = 0.85). However, eGFR had a small but statistically significant effect on outcome (OR 0.99; 95% CI: 0.98-1.00; p = 0.02). CONCLUSIONS This study has shown that more people who undergo cataract surgery have diabetes than previously reported. Also, people with diabetes are at higher risk of developing complications than previously reported. HbA1c concentration was not a factor in these adverse post-operative outcomes. However, eGFR was a predictor of risk. More focus should be placed on pre-operatively optimising co-morbidities than diabetes control in those undergoing cataract surgery.

Abstract
Background Cataracts is the major global causes of blindness and a vision-affecting disease of the eye. Cataract surgery is a curative and cost-effective intervention. The number of people who undergo cataract surgery has increased rapidly. Hence, this study was aimed to determine predictors and the time of recovery of cataract patients after cataract surgery by using Simi parametric models of survival analysis. Methods A retrospective cohort study was conducted from January/01/2015 and January/30/2019. STATA version14.0 statistical software was used for analysis. The Kaplan-Meier survival method and log-rank test curves were applied. Weibull regression was used and adjusted hazard ratio 95% CI with a value of p less than 0.05 was used to identify a significant association. Results Two hundred twenty three cataract patients were recovered from cataract, 72.6% (95% CI 69.8%–75.9%). The overall median survival time was 23 weeks (IQR = 16 to 35) with (95% CI, 21%–25%). aged between 16 and 30year (AHR = 1.20 CI; 1.07–2.36), age 31 to 45 (AHR = 1.24 CI; 1.08–1.54), urban dwellers (AHR = 1.59; 95% CI, 1.18–2.14), medium visual acuity (AHR = 4.14 CI; 2.57–6.67), high visual acuity (AHR = 5.23 CI; 3.06–8.93), Secondary cataract (AHR = 2.59 CI; 1.01–3.02), traumatic cataract (AHR = 1.75 CI; 1.01–3.02), extra capsular cataract extraction surgery (AHR = 1.43 CI; 1.07–1.94),and diabetes mellitus (AHR = 0.75, CI; 0.41–0.96) were notably associated with time to recovery. Conclusion Time to recovery in the study area was slightly higher as compared with the global cut of time. Cataract patients with comorbidity of DM had lower recovery time. A 72.6% cataract patients were recovered and 27.4% of were censored from cataract. The overall median survival time was 23 weeks and the mean recovery time of the patients was 23.24 weeks. A significant difference seen in the recovery rate among cataract patients with/out diabetes mellitus. Time to recovery in the study area was slightly higher.

Abstract
PURPOSE To evaluate the early changes in retinal microcirculation after uncomplicated cataract surgery using an active-fluidics system. MATERIALS AND METHODS Patients underwent uncomplicated cataract surgery for both eyes were enrolled. The two eyes of the patients were randomly assigned to two groups, the active-fluidics group and the gravity-fluidics group. One eye using an active-fluidics system, and the other using a gravity-fluidics system. Optical coherence tomography angiography (OCTA) was performed at 1 day, 7 days, 30 days, and 90 days after surgery. RESULTS Fifty eyes (25 patients) were included in the final analysis. A significantly lower cumulative dissipated energy (CDE), estimated fluid usage (EFU), and total aspiration time (TAT) were observed in the active-fluidics group (all P<0.05). The superficial vessel density at parafoveal region increased at 7 days and 30 days after cataract surgery in the eyes of both the active-fluidics and gravity-fluidics groups, with the fluctuation in eyes of the gravity-fluidics group more significant. The vessel density of deep capillary plexus remained stable during the follow-up period. Significant changes of retinal thickness in macular region (fovea, parafovea) were observed in eyes of the gravity-fluidics group through the comparison of corresponding values at different time points (p = 0.008, 0.005). No significant change in retinal thickness was observed in eyes of the active-fluidics. CONCLUSIONS Retinal microcirculation and thickness were disturbed after cataract surgery using the gravity-fluidics infusion system. The active-fluidics system not only improved the surgical efficacy but also protected the retinal vasculature during cataract surgery.

Abstract
Background To determine whether patients with severe vision impairment due to advanced age-related macular degeneration (AMD) benefit from bilateral cataract surgery in terms of vision-related quality of life (QoL). Methods A prospective interventional single-center study. Ten patients with severe vision impairment due to advanced bilateral AMD were included. The preoperative corrected distance visual acuity (CDVA) was ≥1.0/≥1.0 LogMAR units on Snellen chart and <20/<20 points on Early Treatment Diabetic Retinopathy Study (ETDRS) chart. Patients were not on active treatment for wet AMD as the treatment was expected to have no effect or benefit. The patients were scheduled for immediate sequential bilateral cataract surgery, with target refraction emmetropia (SN60WF, Alcon). Vision-related QoL was measured with National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) preoperatively, at 3 months and 1 year. Results The mean age of the patients was 82.5±6.2 years. The mean NEI VFQ-25 overall composite score changed from 44.0±7.1 preoperatively to 54.9±13.7 at 3 months and to 56.9±15.6 at 1 year (P=0.045, Friedman test). During the 1-year follow-up, there was an improvement in the subscale scores indicating difficulty with peripheral vision, mental health symptoms, and role difficulties due to vision (P<0.05 for all, Wilcoxon sign-rank test). Conclusions Cataract surgery may improve the vision-related QoL in patients with severe vision impairment due to bilateral advanced AMD.

Abstract
Background To evaluate macular microvascular changes and associated factors in diabetic patients following uncomplicated phacoemulsification surgery. Methods In this prospective observational study, we enrolled diabetic patients and non-diabetic controls who underwent phacoemulsification surgery. Participants were examined at postoperative day 1 (POD1), 10 (POD10), 30 (POD30), and 90 (POD90), using macular 3x3mm OCT angiography scan (RTVue-XR Avanti; Optovue, Inc., Fremont, CA). Integrated automated algorithms were used to quantify parafoveal vessel density (VD) in superficial capillary plexus (SCP) and deep capillary plexus (DCP). To minimize measurement bias, subjects with corneal edema or capsular opacity at any postoperative visit were excluded. Results The study included 21 eyes of 21 diabetic patients and 21 eyes of 21 non-diabetic controls. In diabetic patients, no significant change in SCP-VD could be detected (P = 0.57); DCP-VD reduced from 50.24 ± 2.33% at POD1 to 48.33 ± 3.07% at POD30 (P = 0.019), and restored to 50.74 ± 3.44% at POD90 (P = 1.00). The DCP-VD change at POD30 in diabetic patients (− 1.90 ± 2.61%) was significantly different from that in controls (1.31 ± 2.61%) (P < 0.001). The amount of DCP-VD reduction was correlated with foveal and parafoveal thickening (r = 0.431, P = 0.051 and r = 0.514, P = 0.017, respectively), high cumulative dissipated energy (P = 0.032) and increased hemoglobin A1c concentration (P = 0.037). Conclusions Phacoemulsification in diabetic patients caused transient reduction in DCP-VD, which was associated with poor glycemic control, surgical trauma, and postoperative macular thickening. Our results added a new dimension to our understanding of the complex biologic effects of cataract surgery in diabetic subjects.

Abstract
PURPOSE This study aims to determine whether elevated central macular thickness (CMT) before uncomplicated cataract surgery may be a risk factor for developing cystic macular edema (CMEs) as measured by Cirrus-OCT and defined as the presence of macular intraretinal cysts. METHODS A prospective study in Hospital Universitario Poniente, Almeria, Spain, where 379 patients were included for optical coherence tomography (OCT) before cataract surgery, the following day, at 1 month and at 3 months and the presence of macular intraretinal cysts assessed by OCT. Patients with known risk factors for developing CME and patients who developed major surgical complications were excluded. RESULTS One hundred seventy-nine patients completed the study. The pre-surgical CMT was 257.75 (20.60) μm measured by Cirrus-OCT. After 1 month, there was an average increase in CMT of 277.86 (45.29) μm, and this increase in thickness decreased after 3 months to an average value of 267.86 (20.17) μm. There were 10.34% of patients with cysts in some of the controls after surgery. This study proposes a binary logistic model to predict the presence of CME depending on the pre-surgery CMT. The cut-off point was 260.5 μm. CONCLUSION Patients with pre-surgical macular thickness > 260.5 μm measured by Cirrus- OCT before cataract surgery, no known risk factors for developing CME and no major surgical complications presented 9.08 times more probability to develop macular intraretinal cysts after uncomplicated cataract surgery.
